The purpose of this paper is to show how much the subjects based on the mathematics and statistics contribute to the curriculum and the education of the students majoring in engineer of the Computer-Software department, and to recognize the roles of mathematics and statistics in the Computer-Software department. In order to advance the world-class Computer-Software department, it is necessary for Math/Stat to ensure the role as a basis for the Computer-Software majors as well as to extend its role to relate the core studies of the Computer-Software majors. Consequently, the recognition of Math/Stat in the Computer-Software major will enable to establish the short or/and long-tern plan for student education.

The purpose of this study is to introduce the math-clinic programs which offer to engineering students and to compare the subject satisfaction between participants and non-participants. Five math-clinic programs are operated and 1397 students took part in this study. As a result, the Likert-type scales of satisfaction with three programs; the exercise problems solving class, the tutoring program and the achievement tests, were 4.07, 4.05 and 3.95, respectively(5-point Likert-type scale). And we found that the participants expressed higher subject satisfactions than nonparticipations did.

Polynomials are one of most important and widely used numerical tools in dealing with a smooth function on a bounded domain and trigonometric functions work for smooth periodic functions. However, they are not the best choice if a function has a bounded support in space and in frequency domain. The Prolate Spheroidal wave function (PSWF) of order zero has been known as a best candidate as a basis for band-limited functions. In this paper, we review some basic properties of PSWFs defined as eigenfunctions of bounded Fourier transformation. We also propose numerical inversion schemes based on PSWF and present some numerical examples to show their feasibilities as signal processing tools.

The purpose of this study was to research and compare teachers' preferences for 'Great Math Class' by region and gender. The research was conducted on 261 high school math teachers by using non-probability sampling. As the results of the study, regional preference had no statistically significant difference in all four factors of 'Great Math Class' while gender preference had statistically significant difference only in the factor of teaching (methods) and learning methods. Both region and gender had statistically significant positive (+) relationship with preference for all four factors. This implies that it is necessary to consider socio-cultural factors rather than teachers' perception on class for regional differences in academic achievements in mathematics.

최근 독서 장애인을 위한 국제 디지털 음성 도서 표준인 DAISY를 통해 장애인의 고등 교육을 위한 연구가 활성화되고 있으나 그림이나 수식과 같은 특수요소는 음성도서로 만들어 활용하기 어렵다. 이를 위해, 본 연구에서는 중학교 교과과정에 포함된 내용 MathML 엘리먼트에 대한 한글 독음 규칙을 정의하였다. 또한, 정의한 한글 독음 규칙에 따라 내용 MathML로 표현된 수식을 독음 텍스트로 변환하는 프로그램을 XSLT로 구현하였다.

스마트 디바이스 내에 내재된 암호 알고리즘의 이론적인 안전성이 보장되었더라도 연산 수행 시 소모되는 전력소모, 전자기파와 같은 물리적 정보와의 관계를 분석하는 부채널 공격에 대해 취약하다. 이에 대해 부채널 공격의 대표적 대응 기법으로 셔플링 기법과 마스킹 기법이 제안되었다. 특히 셔플링을 활용한 대응 기법은 효율성을 최대한 유지하면서 분석의 난이도를 높이는 기법으로 잘 알려져 왔다. 본 논문에서는 AES 대칭키 암호의 부채널 대응 기법으로 8가지 AES 구현 기법을 셔플링 하여 구현할 경우 부채널 분석에 미치는 영향에 대해 연구하였다. 실험 결과 실제 기대되어지는 분석 난이도는 셔플링을 하지 않은 것에 비해 64배 정도 공격 복잡도가 높아져야 하지만, 실제는 7배정도의 공격 복잡도 증가로 분석이 되었다.

SENKs (Students who Emigrated from North Korea to South Korea) are exposed to the general problem of Su-Po-Ja(mathematics give-uppers) as well as their own difficulty in learning mathematics. In this study, we conducted the FGI (focus group interview) in order to examine the recognition on mathematics teaching and learning in South Korea with 6 SENKs and 3 teachers who teach the SENKs. As a result, it was found that SENKs' had difficulties in understanding math because of the differences in math terminology used in South and that in North Korea, the unfamiliar problem situation used in math lesson, and the shortage of time for solving math problem. And the teachers reported that they had difficulties in teaching great deal of basic math, SENKs' weak will to learn math, and SENKs' lack of understanding about problem situation because of the inexperience about culture and society in South Korea.

This study was conducted with the aim to develop and improve the assessment literacy of teachers which enables it to develop and utilize the assessment items using a wide range of contexts on the basis of an understanding of math contents and mathematical process specified in the math curriculum and to analyze the results in an effective way. To analyze the changes in the development and improvement of the assessment literacy of preservice math teachers, the author of this study, using PISA items and assessment framework, analyzed the changes through the 1st and 2nd development of assessment items. The results showed the assessment literacy of preservice math teachers and their ability have been improved, implying that there is the necessity to develop a wide range of programs to improve the assessment literacy of preservice math teachers and provide such programs on a regular basis, which will facilitate effective math teaching and learning.

This study was designed to gain insights into contemporary secondary mathematics curriculum revision in Korea. The two secondary mathematics curriculum reports submitted in the 1920s, the Kilpatrick Reports and 1923 Reports were compared and contrasted as the origin of recent math wars, and their backgrounds, committee members, viewpoints of math and math education and contents were analyzed to understand the perspectives of the two extreeme parts. Kilpatrick Reports was selected at that time, but nevertheless 1923 Report had taken a role of guiding secondary mathematics in US until the New Math era. The direction and process of mathematics curriculum revision were suggested based on the analysis of reports' short- and long-term influences. A close examination of the curriculum revision process in US and in Korea and the implications from the results are also included in the suggestion.
